摘　　要：通过考察汽液固三相反应器内由Fe(OH)_2制备氧化铁黄晶种的工艺条件,对影响氧化铁黄晶种生成速率的因素进行了研究和探讨,并对实验数据进行拟合得出实验范围内各因素对平均反应速率影响的关系式。结果表明,常温下,在三相反应器内,增加空气流量、液相流量、原料液浓度及反应压力,降低Fe(OH)2胶体颗粒粒径,均有利于氧化铁黄晶种的生成。实验获得的拟合参数对今后氧化铁黄颜料工艺条件的优化和反应器的设计具有一定的指导意义。Through the study on preparation of yellow iron oxide crystal seed from Fe（OH）2 in a three phases reactor, the process conditions of the preparation process was performed to study the factors that influence the formation rate of yellow iron oxide. Linear fitting was carried out to obtain the formula. Experimental results show increasing the air flow rate, liquid flow rate, feed concentration and reaction pressure, or reducing the colloidal particle size of Fe （OH）2, facilitate the formation of yellow iron oxide crystal seed in the three phases reactor at room temperature. The results should be useful to the process condition optimization and reactor design of yellow iron oxide pigment.
